This is super cool, I wish it went more in depth as to how the mechanism works. I assume it contains some kind of camshaft system for each digit that encodes a fourier series? Really beautiful
- GuB-42 5y agoIt doesn't look like a Fourier series. It couldn't do sharp angles if it was (like for the 5 or 7). Looking at the pictures, it looks like a two axis parallel robot where the arms are controlled by a cams with complex shapes. The cams can be seen in picture 11/16.

- drdeadringer 5y agoI recall a young man building a portion of the 'Game Of Thrones' theme video. Think watching a real-life mechanical, clockwork Winterfell or Kings Landing twisting and rising all out of pop-up flatwood in your spare bedroom. I've tried a quick search on Youtube for the video but couldn't easily find it. The kid's friend joked about how soon HBO would hit him up on copyright.

I imagine there's some sort of slider to engage a cam for the "current digit" so when the redraw triggers the selected cam is the one used for the motion. Many automata use a similar design to to achieve preprogrammed movements, like writing, drawing or playing an instrument.
